If you want to fly a Pitts, and have a holiday in a great part of the world at the same time, try Airborne Aviation just outside Sydney. At current Australian $ values the $428 hourly rate is about 183 GBP/hr. Sign a declaration that you're working towards a CPL and the GST comes off, bringing the price to about 165 GBP/hr. That's about 30% less than the Decathlon I flew at Kemble last week. They've also a Citabria if you want to do a couple of hours tailwheel time first in something less challenging than the Pitts.
